To all whont it may concern.-

Be it known that I, PHILIP LINDEMEYR, a resident of Baltimore, in the State of Maryland, have invented certain new and useful Improvements in VesseLC/aps; andl do herebydeclare the following tobe a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

{0 The invention relates to caps for closing bottles and other vessels, and has for its object to improve the means of securing the particular class of caps and for removing the same; and it consists in the construction herein described and pointed out.

In the accompanying drawings, Figure 1 is a'perspective of the cap appliedto a bottle mouth and'neck. Fig. 2 is a central longi-' tudinal section. Fig. 3 is a side view of a modified cap with a stripper-wire.

Numeral 1 denotes teeth formed on the edge of a bottle-cap. These as represented are approximately ti-shaped, but may be U- shaped or have other analogous forms.

2 denotes a groove formed in. the neck of a bottle below its mouth and situated between two circumferential ribs or rings.

3 denotes a shoulder on the lower side of the lower rib or ring a, which bounds said 3o groove on its lower side.

5 denotes a sealing-disk, of cork or other material, which preferably will be used, though its use is not of the gist of the inn provement.

Then the cap is applied to abottle, its teeth 1 extend below the shoulder 3 and are bent thereunder to hold the cap in place. In this operation the resiliency of the cork cooperates and adds to the security of the closure.

The cap-teeth are of such length that the spaces between them extend above the ring 4 and preferably to or abov e the upper line of the groove. 'Said spaces should not, however, extend so high nor the teeth be so long as materially to impair their holding power when bent under shoulder 3, whereby means, such as a band or ring, would be made necessary to hold them to the bottle-neck. Caps having short holdingteeth engaged with shoulders on bottle-neckshavebeen proposed, and such feature of construction is not of of the tool traveling in the groove.

the present invention, except as combined. with means substantially such as herein do scribed for disengagement of the teeth and removal oi. the cap.

By my improvement the groove guides the point of thestripping instrument 7.1: tool, it such be used, around under the teeth :hether the bottle be rotated or the tool pushed or pulled about it, the bottle remaining eon paratively stationary, or whether the rotary movement of the bottle be combined with. a thrust or pull of the tool. In case of softinetal caps the teeth can be rapidly disengaged with safety to the operator, the point In case of more rigid material, such as steel, the teeth can be loosened one at a time in succession and more slowly on account of the greater resistance, but in such case also the groove receives and guides the tootpoint. The improvement lessens very decidedly the danger of auinjurious slip of the pointed tool heretofore used for an analogous purpose, and it obviates the crimping of the cap edge to pro vide for the use of a stripping-tool, and in connection with such advantage it also obviates the necessity of a separate securingband and the exposure of the teeth, asillustrated in British Patent No. 15,8 10 of A. D. 1880. It a stripping-wire be used, it may be attached to one of the teeth and lie in the groove and need not extend more than. half way around the bottleneck.

6 (see Fig. 3) denotes a wire or cord secured.

to one of the teeth and situated in the groove. Its free end extends out between two te th and preferably is provided with a loop 8 to receive a nail, pencil, or other like article, which can be conveniently used to pull the wire in stripping the cap from the bottle. The use of a nail or the like is not essential and'neither is the ring, though it provides a convenient fingenhold. It is preferred that the wire, exclusive of a ring and of the wirefastening, have a length not less than half the circumference of thehottle-neck, but the improvement is not limited in this respect.

In some cases the groove 2 can he tilled with a sealing material, the wire being covered or partly covered thereby. In others a string er the like saturated with a sealing material and surrounding the entire neck can be employed,

with advan e, and particularly if no sealing-disk 5 is seed.

The use a stripping wire or cord is not esscn tial tot e main part of the improvement, since if suctdevice is omitted a pointed instrument can be inserted between the teeth to pull or pry them out of engagement with the bottle. i

The provision of a shoulder 3 to receive the inwardly-bent ends of the teeth, said teeth fitting under the shoulder and holding the cap on the bottle without other means, combined with a groove or space 2 in the bottle-neck to admit between the teetna device for releasing them and stripping off the cap, is important. By this construction the points of the teeth are guarded by the shoulder 3, and the spaces between the teeth are left unobstrncted for the use of a pointed-"tooth detaching implement, the groove cooperating in this particular, said groove being adapted to receive a sealing material,if desired. The stripper wire or cord is not necessary either to secure the oap'or to removeit and may, if preferred, be dispensed with, since the cap is secured by the bent teeth, each of which extends over the groove, so that a pointed instrument can be inserted under it and that whether either astripper-wirc or scaling material, or both, be in the groove. j

So far as concerns securing the cap and removing it when desired the groove need not extend entirely around the vessel,and the cap securing function of the teeth is independent of the groove.

In the construction set forth in said British patent. the projections on the lower edge, because of their-comparative length and size, may more properly be styled logs than teeth, since they extend considerably above the groove that separates the two ribs and also to a considerable distance below the lower rib, being so long as to preclude turning their lower ends into the angle between the nib and the bottle-neck and fit the rib, as by my constructionl Further, the extension of the legs and the spaces between them to close prox- 1 irnity to the bottle-mouth and to a considerable distance above the roove would weaken i the holding capacity of the legs if they were depended upon to hold the cap upon the bottle. i Having thus CiGSOX'lilEiti my in volition, what lelaim asnew, and desire to secure by Letters i Patent, is- 1. The combination of a vessel having two i l l l rings near its mouth separated by a circnmfercntial groove,with a cap having in its lower edge a series of teeth separated by spaces ex tending over thegroove and terminating near it, said teeth being bent under the under side of the lower ring with their bodies fitting said under side and their extremities situated i'n the angle between the rib and bottle-neck to hold on the cap and also guard the ends of thcteeth, allsnbstantially as set forth,whereby an instrument can be introduced into the groo re between any two adjacent teeth and nided by such groovein stripping aplnrality of teeth in siiccession from the vessel.

2. The combination of a vessel having two rings near its mouth separated by a circumferential groove, with a cap having in its lower edge a series of teeth separated by spaces extending over the groove andterniinating near it, said teeth being bent under the under side of the lower ring with their bodies fitting said under side and their extremities situated in the angle between the rib and bottle-neck to hold on the cap and also guard. the ends of the teeth, and a stripping-wire sitnatcd in the groove and secured to one of the teeth and extending about one-half the circumference of the vessctneclc.

In testimony whereof I have signed this specification in the presence of two snbscribing witnesses.
